    How to pass PS header data to pdfmark?

      Hope this is the right place for this question:

       

      I currently use a bit of PostScript in Distiller's epilogue.ps file to add my name as "Author" to all my PDFs as they are distilled:

       

      [ /Author (My Name) /DOCINFO pdfmark

       

      So far, so good.

       

      Now what I want to do is automatically pass the data in the header of the PostScript file (such as %%Title, %% Creator) to the epilogue file.

       

      e.g. something like this:

       

      [ /Title TitleVariable /DOCINFO pdfmark

       

      so that a .ps file with a header line

       

      %%Title: My File.file

       

      becomes a PDF file with Title: My File.file

       

      Is this possible?

       

      Hope this makes sense.

       

      At the moment, the three "main" PDF metadata fields are always empty, and it's a pain having to fill them manually.

          I don't think that standard PostScript interpreters parse the comment lines automatically so that you would have populated variables/strings available to your PostScript program after the %%EndComments line. (maybe Dov Isaacs knows for sure).

           

          One alternative would be to add at the end of your epiloque a procedure that reads lines in from "currentfile" as strings until "%%EndComments" is found and parses the strings (looking for strings that start with "%%Creator:", "%%Title", etc. and defining your own variables based on the value portion of the strings.

           

          Redbook example of currentfile useage:

          /str 100 string def

          currentfile str readline

          here is a line of text

          pop /textline exch def

           

          You would have to be a little bit fancier than this but I hope the concept makes sense.
